States must collect, coordinate, and use K-12 and postsecondary data to track and improve the readiness of graduates to succeed in college and the workplace.

Longitudinal data systems should follow individual students from grade to grade and school to school, all the way from kindergarten through postsecondary education and into the workplace. Such systems would also provide more accurate measures of dropout and graduation rates, and provide the foundation for early warning systems.

For states to evaluate and understand the impact of particular policies around graduation requirements, assessments and preparedness for postsecondary, they must follow students through K–12 into postsecondary and the workforce and establish feedback loops to the relevant stakeholders to make informed decisions that improve policies and practices around increasing student preparedness.
